i tried also this: npm i @ng-bootstrap/ng-bootstrap ---> it's giving me the same error

and this: npm i @ng-bootstrap/ng-bootstrap --legacy-peer-deps ---> it's giving me the same error

and this: npm i @ng-bootstrap/ng-bootstrap --force ---> it's giving me the same error

i tried to update angular: ng update @angular/cli @angular/core

But still not working

Answer 1

尝试删除您的 node_modules 文件夹和您的 npm 缓存，然后重试

Answer 2

the Message say to you use angular version @14.0.5 it's not compatible with ng-bootstrap version

solution is: use @angular/cli@13.0.0 @ng-bootstrap/ng-bootstrap@12.1.2

compatibility table: https://ng-bootstrap.github.io/#/getting-started

now, to sol this problem i used: npm i -g @angular/cli@14.1.0 and ng add @ng-bootstrap/ng-bootstrap@13.1.1
